NEW YORK (CBS) — CBS will present the Campaign 2012 season’s first network broadcast of a Republican Presidential Primary debate on Saturday, Nov. 12, beginning at 8 p.m. ET/5 p.m. PT. The event will also be webcast from CBSNews.com with an additional 30 minutes online for post-debate political analysis.

Saturday will be the first time Texas Gov. Rick Perry appears on stage with his fellow GOP presidential rivals following Wednesday’s Republican debate in which Perry couldn’t remember the third federal agency he had pledged to eliminate. Although he was at the top of the polls when he entered the race in August, Perry’s standing dropped after a series of poor debate performances in September.

CBS News’ Scott Pelley and the National Journal’s Major Garrett will moderate the evening’s discussion, which will focus primarily on national security questions. Wofford College in Spartanburg, S.C., will host the event held in conjunction with the South Carolina State Republican Party.

“Scott Pelley and all of us at CBS News look forward to a spirited discussion of the issues with all of the Republican candidates in Spartanburg,” said David Rhodes, president of CBS News.

“This debate will examine the critical questions of America’s role in the world, now and in the future,” said National Journal editor-in-chief Ron Fournier.

During previous Republican debates, the main eight GOP candidates have sought to define themselves against each other and President Barack Obama. The CBS News/National Journal debate will reveal the candidates’ views on wide-ranging foreign affairs topics, such as the wars in Afghanistan and Iraq, the changes throughout the Middle East, Africa, and Asia, and the global war on terror.
